A buddy of mine is trying to put an ECU from a 95 4-banger 5-speed in 94 of the same configuration. Someone told him that those are different and he needs to look at those numbers on the side of the unit. Is that true at all? Or it's to make sure it is not the unit from 4.0?
95 YJ Rio Grande 2.5L 5-speed (We're at point "A". Where is point "B"? Who gives a sh..!? )
02 Triumph Sprint RS 955i (speed junky)
